The EXL Inc. prerender server offers a simple configuration-free Dockerized server for prerendering single page apps for search engines, bots, and other automated systems that suck at/cannot render SPAs properly. The server uses puppeteer (which in turn uses headless google chrome) to actually render the pages.

QUESTION
I need help debugging Webpack's Compression Plugin.
SUMMARY OF PROBLEM
- Goal is to enable asset compression and reduce my app's bundle size. Using the Brotli algorithm as the default, and gzip as a fallback for unsupported browsers.
- I expected a content-encoding field within an asset's Response Headers. Instead, they're loaded without the field. I used the Chrome dev tools' network tab to confirm this. For context, see the following snippet:
- No errors show in my browser or IDE when running locally.
WHAT I TRIED
- Using different implementations for the compression plugin. See below list of approaches:
- (With Webpack Chain API)
ANSWER
Answered 2021-Sep-30 at 14:59It's not clear which server is serving up these assets. If it's Express, looking at the screenshot with the header X-Powered-By
, https://github.com/expressjs/compression/issues/71 shows that Brotli support hasn't been added to Express yet.
There might be a way to just specify the header for content-encoding
manually though.

QUESTION
I'm learning nextjs and read in a few places that nextjs only prerenders for the first page(How is server-side rendering compatible with single-page applications?)
But when I use the Link
tag and navigate to another page, and view page source, I see it has the html elements that are built using data from getServerSideProps
, but in network tab there's no request for html file, only a get request that receives json data for the page. So if it prerenders only for the first page / on refresh, how does the view page source have the html elements created using react?
ANSWER
Answered 2022-Mar-01 at 09:18NextJS does pre-render to accelerate loading HTML from the server and so the SEO score, but when you are already on the website you do not need to load the whole new page HTML again, it will only un React to change components displayed.
You can see in the network tab on your browser this happening, the first page is fully loaded while the others load a .json file containing informations on ho to change the current page.
Also when you get to see the page source code you make a new request so you get the HTML for the new URL.
QUESTION
All of my angularjs site works with prerender except for the home page. When crawled, it sends back a 404 page. I have reason to believe it is this line of code in my .htaccess file, RewriteRule ^(.*)$ http://service.prerender.io/https://%{HTTP_HOST}/$1 [P,L]
but I am not sure.
ANSWER
Answered 2022-Feb-23 at 14:31The issue turned out to be that the .htaccess file was serving example.com/index.html rather than just example.com when accessing the root of the angularjs app. That in turn didn't play well with ui-router because the $stateProvider doesn't serve filenames at the end of urls without being explicit. Accessing example.com/index.html did indeed cause my page to throw a 404 error $urlRouterProvider.otherwise('404');
Adding the following code fixed my issue.
QUESTION
This question is about architecture more than coding.
Here's the case. In React sometimes we want to hide components. For example, when user opens new page in SPA, when some toast is closed, etc. We can hide them with adding display: none
. Or we can remove them from the virtual DOM.
ANSWER
Answered 2021-Sep-01 at 07:22Well if you want to use lifecycles there are workarounds for that as well. if you are using functional components then you can manage the rerenders using the dependency props.
Its true dom size can slow you down if you use it excessively https://web.dev/dom-size/ But is better if those components are constantly being updated rather then rendering a new component on demand.
If its a list of items and its gigantic i suggest you to take a look at https://react-window.vercel.app/#/examples/list/fixed-size or https://bvaughn.github.io/react-virtualized/#/components/List

...ANSWER
Answered 2022-Jan-30 at 18:00There is no built in timer component, but there are several ways to accomplish this.
JS directiveThe most over-powered way of accomplishing this is to use the DotVVM 3 @js directive to link a JS file into your page and then trigger a NamedCommand from JS. Full documentation is here: https://www.dotvvm.com/docs/3.0/pages/concepts/client-side-development/js-directive/call-dotvvm-from-js. The Javascript you need is (roughly) this:

QUESTION
I'm trying to serve two different versions of a single page application - one, built with a brand new, shiny JS framework, and another built with an older, crummier JS framework. All of the important features and functionality are in the new SPA, and all the non-critical in the older SPA and are in the midst of being ported over.
With this in mind, I'm trying to make the older SPA available via a path, e.g. /old-app
.
The new app resides in /www/new-app
.
The old app resides in /www/old-app
.
